  @mainpage Exif metadata manipulation library and tools v0.4

  @section overview Exiv2 Overview
 
  Exiv2 is a C++ library that provides
  - full read and write access to the Exif metadata of an image through %Exiv2 
    keys and standard C++ iterators 
  - extensive MakerNote support:
      - MakerNote tags can be accessed just like any other Exif metadata
      - a sophisticated write algorithm avoids corrupting the MakerNote: 
         <BR>&nbsp;&nbsp;1) the MakerNote is not re-located if possible at all, and 
         <BR>&nbsp;&nbsp;2) MakerNote IFD offsets are re-calculated if the MakerNote
                            needs to be moved (for known IFD MakerNotes)
      - new camera make/model specific MakerNotes can be added to the library
        with minimum effort in OO-fashion (by subclassing MakerNote or IfdMakerNote)

  - extract and delete methods for Exif thumbnails (both, JPEG and TIFF thumbnails)
  - extensive Doxygen documentation
  - generic lower-level classes to access IFD (Image File Directory) data structures

  %Exiv2 is also a command line program to
  - print the Exif metadata of JPEG images (as summary info, interpreted values, or
    the plain data for each tag)
  - adjust the Exif timestamp (that's how it all started...)
  - rename Exif image files according to the Exif timestamp
  - extract Exif metadata from image files and insert it again
  - extract the thumbnail image embedded in the Exif metadata
  - delete the thumbnail or the complete Exif metadata from an image
